Can FDM really load metadata? I don't think so. With ERPI you can extract metadata from the source systems but you still need to use either EPMA, ODI etc or the applications native metadata load utilities in order to load the metadata. FDM doesn't load metadata just data.

FDM and ERPi are considered one product. They will soo be integrated into one product ... they just seem seperate now during the introduction phase.
Yes it requires 'other' software... all of which is considered part of the EPM Suite. FDM requires 'adapters' to load data into HFM/Essbase/Enterprise/HSF .... but we don't draw a line in the sand for those.

ODI is required reguardless of any ERPi activity. The data extraction for the product ERPi relies on ODI ... as well as the metadata loading. Since Oracle already had this technology built ... ERPi didn't feel the need to re-invent the wheel ... but leverage current software/technologies to achieve its goal.

Firstly I would suggest you or your client become educated in what is actually required to be purchased. I think you are providing false information about the licensing of ODI. As already mentioned ODI is REQUIRED+ for ERPi.
